Care Guide
Preserve Hair Quality & Row Comfort
Simple, consistent aftercare helps Vietnamese human hair stay smooth while reducing stress around the row and attachment points.
Clean the scalp and lengths carefully without vigorous rubbing around the row.
Support the row at the root and brush from ends upward with an extension-safe brush.
Avoid oils, masks and heavy conditioner directly on the attachment points.
Ensure the scalp and row are fully dry after washing before styling or sleeping.
Schedule professional move-up checks according to hair growth and the selected Weft system.
Safe Removal
Professional Weft Removal
Protect the client’s natural hair and reusable extension hair by removing rows only with the correct tools and professional technique.
Identify the existing row method before beginning.
Release beads, stitching or micro rings one attachment at a time.
Support the natural hair and avoid pulling the weft free.
Remove any thread or residue gently and cleanse the natural hair.
Inspect the scalp and the weft before planning maintenance or reapplication.
